Posted by David Croft on 05 November 2018 07:50 PM
Please be advised of the following Christmas moratorium scheduled on
our network.

Start date: Tuesday, 11th December 2018
End date: Friday, 4th January 2019

Purpose:

In line with industry best practice, we and our suppliers will be
instituting our annual change freeze between these dates in order to
protect customer services.

Services affected:

All.

Impact:

There will be an moratorium on changes across our network during this
period. Provision activities may be delayed and lead times will be
impacted if they fall within or after this window. Repair activities
will not be affected.

If we carry out any maintenance activity during this window, it will
be for emergency reasons and will be carried out to protect customer
service and the network from an uncontrolled loss of service.

Please ensure any new orders are submitted in good time to avoid being
affected by this window.

Please note that a few of our suppliers have extended moratoriums
greater than the above time period and our ability to deliver certain
orders may be impacted by this. Customers will be advised at the point
of order if this affects them.

Regards,

David Croft

[Core Network] EMERGENCY Maintenance window 10th July 2018
Posted by David Croft on 09 July 2018 05:56 PM
Please be advised of the following maintenance window scheduled on
our core network:

Start date: Tuesday, 10th July 2018
Start time: 22:00 BST (UTC+0100)
End time: 04:00 BST (UTC+0100) Wednesday

Purpose:

Our emergency engineering works this past weekend were successful with
one exception: one router could not be replaced due to an
incompatibility with our long range fibre SFPs. The original router
was therefore returned to service. This incompatibility was not
detected during testing as the lab links were short range.

This maintenance window is to attempt the router replacement again
with new optics that are arriving tomorrow. Replacement optics will be
installed and the new replacement router brought into service after
testing.

Services affected:

Cloud Ethernet customers single-homed out of Interxion LON1 (CLBIS02).

Impact:

HIGH - Customers with a single connection to our Interxion LON1
(CLBIS02) PoP will experience an interruption in service while the
device is replaced.

Please note: This maintenance window is being declared as EMERGENCY
without the normal notice period due to the need to perform this work
urgently in order to prevent a recurrence of the outage of 22nd May.

Regards,

David Croft
